We’re in that evaluation phase right now where we need to test whether our critical processes can work on an open-source BPM platform without requiring heavy developer involvement. Management wants to know if we can actually validate this before we commit to a full migration.
The question I keep running into is whether a no-code/low-code builder can really handle the complexity of our workflows. We have some processes that are pretty intricate - they involve multiple decision points, data transformations, and error handling. I’m skeptical that a visual builder can capture all of that without developers coming in to write custom code.
What I’ve been reading suggests that there are platforms that let you recreate workflows visually and then compare them side-by-side with your current implementation. The promise is that this lets non-technical people participate in the evaluation, which would actually help us get stakeholder buy-in before we make any expensive commitments.
But I’m wondering about the realistic timeline. How long does it actually take to recreate a critical workflow using a visual builder? And what percentage of your workflows actually end up requiring custom code tweaks anyway?
Has anyone actually gone through this process of recreating workflows in a no-code builder to evaluate a migration, or does it always turn into “we need a developer to make this work”?
We did exactly this when we were evaluating whether to move from our legacy BPM system. I’ll be honest - it worked, but not how I expected.
The no-code builder was actually really effective for the first 70% of our workflows. The basic stuff - data entry, simple conditional logic, notifications - that all mapped over pretty cleanly. The visual representation made it obvious what each step was doing, which was useful for discussing with business stakeholders.
Here’s where it got real though. About 30% of our workflows had special logic or edge cases that required either custom code or workarounds. Things like handling API responses that don’t fit the standard format, or business rules that were hardcoded in the old system that nobody had documented. For those, we needed developer involvement, but it wasn’t as bad as I feared. We could show them a mostly-working visual workflow and say “we need to handle this specific case here,” instead of them having to understand the entire process from scratch.
What helped us was attacking this gradually. We started with the simpler workflows first, got the team comfortable using the builder, and then tackled the complex ones. By the time we got to the tricky stuff, people understood how the tool worked and could communicate better about what needed customization.
Timeline-wise, the simple workflows took us about half a day each to recreate. The complex ones took days, partially because we were discussing and iterating with the business owners.
The comparison aspect was super valuable. Having both the old and new workflows visible side-by-side actually exposed some things we were doing in the legacy system that didn’t make sense anymore. Sometimes that meant simplifying the new workflow. Sometimes it meant realizing we were missing a step.
Yes, we did this and it’s genuinely useful, though the timeline depends on workflow complexity. Simple workflows took us about 2-3 hours each to map out in a no-code builder. Our more complex processes with multiple error paths and conditional routing took more like a full day or two per workflow.
The key is that visual builders are actually better at showing what’s happening than reading through XML or code. It exposed process inefficiencies we hadn’t noticed before. What looked complicated in the old system sometimes turned out to be unnecessary steps that we could cut.
For our evaluation, we focused on our top 10 workflows by volume rather than trying to recreate everything. That gave us enough data to understand whether the platform could handle our patterns without spending weeks in recreation mode.
Developers did need to get involved for some edge cases - custom data transformations and API integration logic - but that was maybe 20% of the work. The no-code tool handled 80%. If you’re smart about which workflows you prioritize, you can validate the migration without needing custom code for everything.
The visual builder approach is genuinely effective for evaluation purposes, but it has limitations you should understand going in. Most workflows can be represented visually - the graphical representation is actually clearer than looking at process diagrams or code. Where it breaks down is with highly specific business logic or system integrations that require custom transformation logic.
In our experience, you can recreate about 75-85% of typical workflows using a no-code builder. The remaining 15-25% requires either custom code or creative workarounds using available tools. The timeline depends on documentation quality - if you have clear process documentation, recreation is faster. If you’re reverse-engineering from an undocumented legacy system, it takes longer.
The comparison value is substantial. Seeing the old and new workflows side by side usually surfaces inefficiencies in your current process. People realize they’re doing steps that aren’t necessary or are duplicative. That’s actually one of the best outcomes of this evaluation - you often find that the new system encourages better process design.
One caution: don’t get stuck in perfect recreation mode. The goal of the evaluation phase is validation, not perfection. A 70% recreation that shows the platform works is more valuable than an 95% recreation that takes twice as long and doesn’t change your conclusion.
We recreated our top workflows visually. Simple ones took 2-3 hours each, complex ones took days. About 20% needed custom code work, but 80% worked fine in the builder. Valuable for stakeholder conversations.
The no-code builder approach actually works really well for this kind of evaluation, and Latenode’s visual workflow builder is specifically designed to make this easier for non-technical teams.
What makes it effective is that you can drag and drop your process logic visually, and the builder translates that into executable workflows. For your critical workflows, you get to see exactly how they’d work without writing any code initially. But here’s the key part - when you hit something that needs custom logic, you have the option to drop JavaScript into specific nodes without rewriting the entire workflow.
We’ve seen teams recreate complex workflows in a matter of hours because the visual representation is so clear. The comparison capability is built in - you can maintain both your current workflow version and the new one side by side, which is exactly what you need for evaluation.
The real benefit for migration evaluation is that a visual builder lets business stakeholders participate in the validation. They can see their process represented clearly and verify that all the logic is captured. That kind of buy-in before migration is invaluable.
Try it with your top 5 workflows first. You’ll probably find that most of them work in the visual builder, and any that need customization are clear about what needs to be handled differently.
